The human problem
PET waste is difficult to return to reusable chemical building blocks.
What changed
- The constraint
- Enzymatic recycling is constrained by activity and operating conditions.
- AI’s role
- A model guided protein mutations for improved performance.
- The observed result
- Engineered enzymes demonstrated PET depolymerization in laboratory experiments.
The human possibility
A possible component of improved recycling processes.
Possible implications are separate from measured outcomes.

Laboratory success does not establish industrial economics or a solution for all plastics.
What this classification does—and does not—establish
Bright’s classification applies to the result described here. It does not certify a product, recommend a treatment, or predict a future outcome. Source publication and real-world deployment are different milestones. This opening record may not include every later study.
A record that can change
Added to the source-checked opening collection.
This is Bright’s catalog history, not a complete history of the research. Future corrections and evidence revisions will be recorded here.
What comes next
Evaluate scale, energy use, and realistic waste streams.
